## Customer Reviews

### ⭐⭐⭐⭐⭐ Flange
*by J***E on 3 March 2026*

Good set! Helpful sizer.

### ⭐⭐⭐⭐⭐ Amazing
*by P***T on 16 January 2026*

### ⭐⭐⭐⭐⭐ A necessity for pumping mums!
*by L***N on 21 July 2025*

Would recommend to anyone pumping, standard flanges on breast pumps are way too big and stopped me from pumping. Would have pumped more if I'd had these from the beginning. The nipple measurement guide really helps with gauging size. Easy to clean, I washed with hot soapy water and threw in the steriliser.
